Robert the Bruce (July, 1274 - June, 1329) was a human who lived in the late 13th and early 14th centuries on Earth. In 1306 he assumed the throne of Scotland, and thus became King Robert I. He ruled until his death in 1329. In the years following his death Bruce would become a national hero to the people of Scotland.
In 2269, when ordered to transport an Excalbian recreation of Abraham Lincoln, Montgomery Scott speculated that the USS Enterprise would next be visited by Robert the Bruce. Overhearing this, Captain James T. Kirk ordered that if that were the case appropriate honors would be rendered to Bruce as well. (TOS episode: "The Savage Curtain")
